Description of key information
A ready biodegradability test has been performed for FPBO according to REACH regulation, the result indicating that the substance is not readily biodegradable, with ca. 51 % biodegradation within 28 days. This is in line with Blin et al. (2007), who found biodegradation of 41-50 % within 28 d for fast pyrolysis oils, and found them to be inherently biodegradable. According to OECD guidelines (OECD, 2006), when the results of ready biodegradability tests indicate that the pass level criterion (in this case, 60 % theoretical oxygen demand) is almost fulfilled, such results can be used to indicate inherent biodegradability of the substance. OECD also notes that it has been suggested the pass level of respirometric tests for ready biodegradability be decreased from 60 % to 50 % (OECD, 2006). The uses of Fast pyrolysis bio-oil (production, distribution and use as fuel) take place in closed systems and involve only accidental direct or indirect releases into soil and water and minor releases into wastewater.
The slowly degrading part of FPBO likely consists of compounds of high molecular weight, low water-solubility and/or several aromatic rings. Such components include lignin-derived compounds (particularly those of high molecular mass), aromatic and polyaromatic compounds (including PAHs) and sterols.
